Ill the author.s opinion the results o))taine(l in this experiment point 

 strongly to the use of acid phosphate as the most profitable fertilizing 

 ino-rodient in of^-ain and ofrass culture. 



Comparative trial of different clover and grass mixtures for 

 seeding, H. J. Wheeler and J. A. Tillikghast {Rhode Idand ASfa. 

 Itj)t. 1S99, pj). 168-170). — A number of grass and clover mixtures 

 were used for seeding different plats for the purpose of determining 

 the relative yields and periods of maturity. 



On the grass plats a mixture of Jj/'ornu.s ineynnls, meadow fescue, and 

 orchard grass was used on one plat, orchard grass alone on another, 

 and Bi'onim hiermi^ and meadow fescue on a third. On the clover 

 plats common red clover and alsike, respectively, were combined with 

 timothy and redtop. The grass plats were ready to cut about 3 weeks 

 before the clover plats. })ut the yields on the latter were more than 

 double those obtained from the grass plats. For practical purposes 

 the combination of clover, redtop. and timothy is believed to be the 

 best mixture tried. On large farms the hay crop can be better cared 

 for if mixtures are used which mature at different dates. 



The G-olden Vine field pea; its composition and yield per acre, 

 J, Stewakt {Utali Std. Bnl. 69, pp. 313-328). — The chemical compo- 

 sition (food value) and yield per acre of the whole plant and the 

 leaves, stalks, and pods at different stages of growth were investigated. 

 "Three-fourths of the plant consists of leaves when it is young and 

 one-fourth of stalks. At maturity a little more than two-fifths are 

 leaves, a little more than one-fifth stalks, and a little less than two- 

 fifths pods. . . . The percentage of leaves decreases from youth to 

 maturity; the percentage of stalk increases until the pods begin to 

 form, and then decreases.'- 



On June 19, when the peas were about 9 in. high, 88. 3 per cent of 

 the whole green plant was water. The greatest jneld of both green 

 and dry matter in the whole plant occurred July 10, after which no 

 further growth of leaves or stalks took place. Two-thirds of the 

 whole crop at this time consisted of leaves. Two weeks later, or Jul}^ 

 2-i. the pods contained their greatest weight of both green and dr}' 

 matter. The yield of dr}^ material Juh^ 10 was, for the whole plant, 

 4,997 lbs. per acre, divided as follows: Leaves 3,347 lbs., stalks 1,391 

 lbs., flowers 259 lbs. When the pods were mature, July 24, the total 

 yield of dr}' matter was 3,496 lbs., divided as follows: Leaves 1.699 

 ibs., stalks 689 lbs., pods 1,108 lbs. 



The peas developed rapidly after the}' had become thoroughly estab- 

 lished. Over four-fifths of the entire weight of the crop on July 10 

 had been produced during the 3 previous weeks. The following taljle 

 shows the percentage composition of the whole plant and of different 

 portions on the da}' when the yield of dry matter was greatest — July 

 10 — and 2 weeks later, when the pods were mature:
